Computer Programming I Evolution of Computers

Mechanical Devices • Pascaline (1642) • Set of gears, similar to clock • Only performed addition • Stepped Reckoner • Gottfried Leibniz • Cylindrical wheel with movablecarriage • Add, subtract, multiply, divide, square roots • Jammed/malfunctioned

Mechanical Devices • Difference Machine (1822) • Charles Babbage • Produce table of numbers used by ships’ navigators. • Never built • Analytical Machine (1833) • Perform variety of calculations by following a set of instructions (or program) on punched cards • Never built • Used as a model for modern computer

Mechanical Devices • Babbage’s chief collaborator on the Analytical Machine was Ada Byron. • Ada Byron • Sponsor of Analytical Machine • One of first people to realize its power and significance • Often called the first programmer because she wrote a program based on the design of the Analytical Machine.

Electro-Mechanical Devices • Hollerith’s Tabulating Machine • Herman Hollerith – used electricity • For US Census • Holes representing information to be tabulated were punched in cards • Successful • Mark I (1944) • IBM & Harvard • Mechanical telephone replay switches to store information and accepted data on punch cards. • Highly sophisticated calculator - unreliable

Electro-Mechanical Devices • These devices were not mass produced. • Not Reliable • Still took time • Hollerith’s machine took 6 years for a general account. • Mark 1 – 51 ft. long, weighed 5 tons

First Generation Computers • Atanasoff-Berry Computer (ABC) • Built b/w 1939-1942 • Used binary number system • Vacuum tubes • Stored info by electronically burning holes in sheets of paper. • ENIAC • Electronic Numerical Integration and Calculator • 1943, 30 tons, 1500 sq ft., 17,000+ vacuum tubes • Secret military project during WWII to calculate trajectory of artillery shells. • Solve a problem in 20 min that would have take a team of mathematicians three days to solve.

What is a Computer? An electronic machine that accepts data, processes it according to instructions, and provides the results as new data.

The Stored Program Computer • Alan Turing & John von Neumann • Mathematicians with the idea of stored programs • Turing • Developed idea of “universal machine” • Perform many different tasks by changing a program (list of instructions) • Von Neumann • Presented idea of stored program concept • The stored program computer would store computer instructions in a CPU.

The Stored Program Computer • Von Neumann, Mauchly and Eckert designed & built the EDVAC (Electronic Discrete Variable Automatic Computer) and the EDSAC (Electronic Delay Storage Automatic Computer) • Designed to solve many problems by simply entering new instructions stored on paper tape. • Machine language (1’s & 0’s)

The Stored Program Computer • Mauchly & Eckert built 3rd computer (UNIVAC - UNIVersal Automatic Computer) • 1st computer language – C-10 (developed by Betty Holberton) • Holberton also developed first keyboard and numeric keypad • First UNIVAC sold to US Census Bureau in 1951

Second Generation Computers • 1947, Bell Lab (Shockley, Bardeen, Brittain) • Invented the transistor • Replaced many vacuum tubes • Less expensive, increased calculating speeds • Model 650 (early 1960s) • IBM introduced first medium-sizedcomputer (Model 650) • Still expensive

Second Generation Computers • Change in way data was stored • Magnetic tape and high speed reel-to-reel tape machines replaced punched cards • Magnetic tape gave computers ability to read (access) and write (store) data quickly and reliably

Third Generation Computers • Integrated circuits (ICs) – replaced transistors • Kilby and Noyce – working independently developed the IC (chip) • ICs • Silicon wafers with intricate circuits etched in their surfaces and then coated with a metallic oxide that fills in the etched circuit patterns • IBM System 360 (1964) • One of first computers to use IC

Mainframes A large computer that is usually used for multi-user applications IBM System 360 one of first mainframes Used terminals to communicate with mainframe

Fourth Generation Computer • Microprocessor (1970) • Hoff at Intel Corp, invented microprocessor • Entire CPU on a chip • Makes possible to build the microcomputer (or PC) • Altair – one of first PCs 1975 • Wozniak and Jobs designed and build first Apple Computer in 1976 • IBM introduced IBM-PC in 1981
